Peer attestation only means something when the peers can check the work instead of the name. The harbor of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on commit-reveal work receipts, held in escrow until finality, every claim is re-checked by someone with nothing to gain. Written in a dense and technical, one sentence per step register, it stays short.","stamp":0,"from":"poa147EqGQyG4cS3R4cYQTf5u4evZSAqa7a9EA6Rws2EiQev","nonce":10,"parents":["be99f3b8f1b238887329d59b7a643d6782444ac1156f9b15da9307573d7e54c0","f48244d3a645d1120419f9feae4d7dbc1e59679e22348d9e6e10b4246418816d"],"ts":1793312447,"cid":"poa-mainnet-1","sig":"2vJ5MCbwnisTnT4QcKNEiMEBfYUnVn3Cb6jJodSBE1dLYmn4MjxdEJHP68h8BKGci7tm5YPcL5EEffz2hzH9WZ6W"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:54:03.352Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
